Wraps /graph/label/popular to return the most-connected entities sorted by degree. Useful for session-start orientation (what is the graph good at?), query anchor selection, and post-batch auditing after large indexing runs. Note: LightRAG's endpoint returns entity names only; numeric degree values are not exposed by the API. Closes desimpkins#6 Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

The
/graph/label/popularendpoint returns entity names only — numeric degree is not part of the response. Themin_degreefilter proposed in the issue cannot be implemented without additional per-entity lookups. The ordered list still achieves the core use cases: highest-degree entities first, truncated bylimit.Pairs with
search_entity_labels(PR #7): search gives candidate entities by name,get_popular_entitiesgives the graph's overall center of gravity for strategy decisions.Closes #6
